Abstract

Mobile broadband traffic has been exploding in wireless networks (400)resulting in an increase of interferences and reduced operator control. Networks (400) are also becoming more heterogeneous putting additional demand in interference management. Scheduler (540) schedules uplink transmissions from UEs (430) based on a load prediction algorithm that typically assumes worst case. However, UEs (430) do not always use full power granted, and thus, much of granted radio resources are wasted. To address these and other issues, technique(s) to accurately predict/estimate other cell interferences and thermal noise separately and to accurately predict/estimate load utilization probability and variance is(are) described. Inventive estimation technique(s) can be used to schedule UEs (430) to more fully utilize available radio resources. Extended Kalman filtering can be adapted for use in estimation providing low order computational complexity.
